I started the day unable to find my key fob (I still had my spare). So I called my dealer and got a price for a replacement. Just the Fob no mechanical key, no programming, $499 !! Holy Cow. I went though the house tipping over chairs and found it under my recliner. I'm so relieved to save the $500 plus that it would cost to replace. Moral to the story: Keep close track of your key fobs, they are serious to replace.
